to find brothers and sisters to other tree trunk
HelloI have a Table with objects [T (identification number, the field number)].
I have another table that links these objects in a structure tree [L (up_id number, down_id number)]. ~ (I need the child of beeing objects in more than one parent) ~.
Get the ID of a certain object (not the root, but it guaranteed not to have only one path to the root).
I have to find all the objects in the entire tree with the same value in the name attribute.
Usully I would go for connect prior down_id = up_id start with up_id is null but in my case there is no entry in L have up_id NULL. : () o
How can I select all nodes in a tree?
Is this possible with a single statement?
Good bye

Subqueries certainly help. They do not have to be in a WITH clause. views online would work in this case.
I have to respect the tree structure, because the table contains several separate trees...
In a tree, each node has only one parent (if any). In my_tree_links, id = 26 has two parents (10 and 20), so this isn't a tree. You not helping yourself or someone else if you say it is.
INSERT INTO my_objects SELECT LEVEL , mod (LEVEL,7) FROM DUAL CONNECT BY LEVEL < 27; /
When end you a statement with a semicolon followed immediately by a slash, then the statement is executed twice. I suppose that this isn't what you wanted. If my_objects.id is not unique, the solution below will have some minor changes.
To limit the results to the nodes that have an ancestor with the target node, you can do a Query of Yo-Yo , where you do a query of bottom-up first, to find all the ancestors without parents of the target node, then do a query from top to bottom, to find all their descendants, like this:
VARIABLE target_id NUMBER
EXEC :target_id := 26;
WITH got_roots AS
(
SELECT id_up
FROM my_tree_links
WHERE CONNECT_BY_ISLEAF = 1
START WITH id_down = :target_id
CONNECT BY id_down = PRIOR id_up
)
, got_descendants AS
(
SELECT id_down
FROM my_tree_links
START WITH id_up IN (
SELECT id_up
FROM got_roots
)
CONNECT BY id_up = PRIOR id_down
)
SELECT DISTINCT
mo.*
FROM my_objects mo
JOIN got_descendants gd ON mo.id = gd.id_down
WHERE mo.value = (
SELECT value
FROM my_objects
WHERE id = :target_id
)
AND mo.id != :target_id -- If wanted
;
Output (where: target_id = 26):
` ID VALUE
---------- ----------
12 5
19 5
5 5
Always tell what version of Oracle you are using. The query above works in Oracle 10 (and), but could be adapted to run on Oracle 9.
Whevever you need to do a CONNECT BY query as a join, it is faster if you can CONNECT BY first, in a separate subquery and join the results for the other tables. This is what the second auxiliary request, got_descendants, is for.
What results would you if: target_id = 8?
The query above, as written, would not include id = 1. If you want, you will need to somehow enter the root ID for example 1, which are never id_down, in the same column with all the id_downs. You can do it with a UNION in the query, but you can change permanently my_tree_links so that these roots have some parent (themselves or some dummy, like NULL).

Is a part of the tree of his own brothers and sisters?
I have a routine that takes an item in the tree selected by a user and loop through all brothers and sisters of the element:
itemRelated = TRUE;treeItemToTest = 0; while ((itemRelated) && (treeItemToTest < totalTreeItems) && (treeItemToTest >= 0)) { /* Check if file is related to the selected file */ AreTreeItemsRelated(panelHandle, treeHandle, treeItemToTest, VAL_SIBLING, selectedTreeIndex, &itemRelated); if (itemRelated) { /* process the item */ /* ... */ ++treeItemToTest; } }
Somewhere between the current version and CVI 2012, our program has stopped working properly. I traced the problem to the call of AreTreeItemsRelated in this routine. In the latest version of LabWindows, this call returns FALSE if treeItemToTest and selectedTreeIndex are from the same point. This is apparently a change in behavior of CVI, 2012, but it is not documented in the help of the function. This change was deliberate?
Yes. You are right. You have run into a scenario that can be very difficult to work around. We try very hard to never break compatibility with older versions of the execution, but sometimes it's inevitable, as in cases like this where a bug is fixed in a new version. Problems occur when there are existing programs which are assuming the existence of this bug and would actually break if it were not for the bug.
The best way to avoid this situation is to use a specific flavour to the version of the runtime of the CVI. It has its drawbacks, of course (for example not automatically benefit from bug fixes in the run-time), but he could sure complicated deployment.
Of course, who isn't really help you now, since your 'program #1' is already deployed using shared execution. Having said that, the best you can do is to replace it, what you can do without uninstalling all of its dependencies, by following these steps.

I want to buy a family music iTunes subscription share with my brothers and sisters. I was wondering if we could so and yet they each be responsible for their own purchases. I want to share a music subscription, but I don't want to pay for their app, music purchases purchases or any apple purchases also. Is this possible or am I dreaming?
Hi TMill41,
Welcome to the communities of Apple Support! If it is possible for individual members of a group sharing of the family to pay for their purchases via gift cards or credits, all costs beyond that will be automatically charged to the organiser credit card by design, as shown in this article:
Make purchases
After you set up your family, anytime a family member throws a new purchase, that it will be charged directly to your account, unless the family member has gift or store credit. First of all, their store credit will be used to pay the invoice total or partial. The rest will be billed to the card of the family of the Organizer. The family Organizer, the revenue generated by the transaction will be sent to you. Learn more about how are charged purchases made on iTunes Store.

How to install brothers and sisters from the master cod
Hello
I am facing a problem,
At first I added the .cod as a resource file in my application, then I read that .cod in byte []. When I try to creteNewModule using CodeModuleManager it gives me the value NULL because of too large this .cod file size (I also tried with the example helloworld cod file and it works correctly).
Now, I used the brothers and sisters of .cod files and try to save, so it works correctly and it gives me my application on the emulator, but while I'm trying to run my application it gives me error - Module 'myApp' has verification errors. Error at startup 'myApp': Module "myApp" contains errors of verification for the emulator of 4.5.Any help is appreciated.

CLEARDATA for brothers and sisters of a Member
Hi all.
There is a need to write a clear script, not the parent but using a child member existing and delete the data of that Member, including his brothers and sisters.
Is there an Essbase feature where you can choose 2 children and he will remove Child1 and Child3?
Parent
Child1
Child2
Child3
I think that you are looking for the function, @ISIBLINGS (membername). This allows you to select a member and his brothers and sisters (@SIBLINGS will return only the brothers and sisters).
You could do something like the following:
Fix (@ISIBLINGS (Member1));
clearblock all;
ENDFIX;
Or you can use cleardata if you do not want to clear all the blocks.

With my script ESTK, users select the model numbers in the list and then the script inserts an element with a model number is entered in an attribute, an element for each selected model.
When you add a large number of elements, each element of extra brother takes a little more then the previous item adds. Adding 250 items may take longer than 3-1/2 minutes or more. During the addition of 20, 50 or 75 items happens quickly, without any noticeable length. It is somewhere in the top 110, this is where that starts to get noticed.
I even used $.hiresTimer and writes the value to the console for each time a model has been added. Because the timer is reset to zero (0) whenever it is called, it was easier to notice than the amount that it incremented from one element to the other got progressively bigger.
Any ideas as to why it takes so long or reflections on what I could do to speed it up?
The structure looks like this:
< PartModels >
Text < NoteText > < / NoteText >
< model ModelNumber = "ABC01" / >
< model ModelNumber = "ABC02" / >
< model ModelNumber = "DEF03" / >
< model ModelNumber = "DEF04" / >
…
…
< model ModelNumber = 'XYZ01-A' / >
< model ModelNumber = "XYZ * B" / >
< model ModelNumber = "XYZ500" / >
< / PartModels >The script is quite simple: scroll a selected model numbers table, add a new item for each model number and value of the attribute, the value of the model number. It's the short version:
Function InsertModelElements (modelsToIns, insElemLoc, GVdoc) {}
var newEleId;
var newElemLoc = insElemLoc;
var elemDef is GVdoc.GetNamedElementDef ("Model");.
for (var i = 0; i < modelsToIns.length; i ++) { / / modelsToIns is the selected model range }
newEleId = elemDef.NewElementInHierarchy (newElemLoc); //ElementLoc based on NoteText first, last, or absent
SetAttribute (newEleId, "ModelNumber", null, modelsToIns [i]); //More feature robust to set the attribute
/ * Which also works for the layout attribute * /.
var vattributes = newEleId.GetAttributes ();
vattributes values [0] [0] = modelsToIns [i];
newEleId.Attributes = vattributes;
/ * At one point, I tried to use a new location of the item to the last inserted element, no change * /.
var newElemRange = setElementSelection (GV_doc, EleId); function that returns the range
newElemLoc = newNewElemRange.end;
}
}
Any help is appreciated.

Trent
Thanks Russ,
I seriously considered trying to copy/paste and started to change the code to do it. But I could not let pass, the answer should be right there in front of me, it's all too long that I worked with this stuff, I am not able to see. Then it dawned on me what's happening.
In a previous test, I put a timer on each action that is closed. For example, I start with a container element that has 200 children of elements, each with a specific/unique model number attribute. All the 200 existing items are deleted and then replaced with 250 new items with a different value for the attribute of model number. The timer was placed after the Element.Delete () and ElementDef.NewElementInHierarchy () methods. What I've noticed with the timer, it's that each deleted item has been removed as fast as the previous item (so it took progressively less and less time to remove an item). And of course the opposite was noted for insert items, each inserted item has taken longer than the previous inserted item.
These elements can be inserted in two areas of the structure, one of the neighborhoods within format rules that affect the formatting and is actually a bit faster. This led me to the cause being ESD format rules. The area that takes more time has quite a few rules of extensible format that apply. Whenever an element is inserted or deleted, FrameMaker through these rules for formatting the content of elements. Given that the rules apply to the parent, first, last, next, previous, etc., FrameMaker must apply the rules of the format to all elements of the structure that the rules (which are extremely complex due to various elements, attribute values, and combinations that can be inserted).
Removal or thinning of the FormatRules in ESD, she becomes faster. But each of the FormatRules are needed. So using app. ApplyFormatRules = false; just before that the elements are deleted and inserted works very well. But the key is to implement ApplyFormatRules return to true before remove the last element should be removed and before inserting the last element to be inserted, so it allows to scroll all the rules of format of ESD for all elements in the hierarchy of these format rules apply to. ApplyFormatRules true and assign the ElementDef until the last item works also [EleId.ElementDef = GV_doc. GetNamedElementDef (insElemType);], but only before all the other functions are performed or different items are added.
doc. Reformat() will not reformat the content correctly after the fact, because the element has been created without the format rules, so it reformats all the contents of the elements without the format rules.
The FDK version which was created 10 years ago had the same problem of slow operation when a large number of items have been inserted, but was still an improvement over having manually insert each item, and then type the value of the attribute, if she had lived with.
He now works surprisingly fast. I hope that my explanation of what I think is happening, including the cause/solution, is understandable.
Sincerely,
Trent Schwartz

Hierarchical Oracle query help needed - path between the crux of two brothers and sisters
I want to find the path between two nodes of oracle hierarchical Table.
Consider the following case-
NodeId - ParentId
=============
1 > > > > > > 0
2 > > > > > > 1
3 > > > > > > 2
4 > > > > > > 3
5 > > > > > > 0
6 > > > > > > 5
Here I want to query the database table that if there is a path between nodes 3 and 5?
The previous query you provided work upwards to the root node.
Here is my expected result, 3-> 2-> 1-> 0-> 5
Yet once if I have a query in the table to get the path between 1 and 3, I want to get out of the way - next
1-> 2-> 3
Therefore, the query works in both cases. Where ADI root can act as an intermediate or no node.
Can you please guide me how I can get it?
Thank you.Hello

I think you want something like this:
WITH bottom_up_from_src AS ( SELECT nodeid , parentid FROM table_x START WITH nodeid = :src_nodeid CONNECT BY nodeid = PRIOR parentid ) , bottom_up_from_dst AS ( SELECT * FROM bottom_up_from_src UNION ALL SELECT parentid AS nodeid , nodeid AS parentid FROM table_x WHERE nodeid NOT IN ( SELECT nodeid FROM bottom_up_from_src ) START WITH nodeid = :dst_nodeid CONNECT BY nodeid = PRIOR parentid ) SELECT :src_nodeid || SYS_CONNECT_BY_PATH (parentid, '-->') AS display_path FROM bottom_up_from_dst WHERE parentid = :dst_nodeid START WITH nodeid = :src_nodeid CONNECT BY nodeid = PRIOR parentid ;
This will show how you can get it from: src_nodeid at dst_nodeid, moving to the top or to the bottom of a hierarchy at a time step. This will work regardless of the fact that
- : src_nodeid is the ancestor of the: dst_nodeid, or
- : src_nodeid is a descendant of: dst_nodeid, or
- both: src_nodeid and: dst_nodeid are the descendants of another node (e.g. 0).
- : src_nodeid is the ancestor of the: dst_nodeid, or
I hope that answers your question.
If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and also publish outcomes from these data.
Explain, using specific examples, how you get these results from these data.
Always say what version of Oracle you are using (for example, 11.2.0.2.0). It is always important, but particularly so with CONNECT BY queries, because each version since Oracle 7 had significant improvements in this area.

According to the Oracle documentation, this error is caused by 'ORDER brothers' and SŒURS clause of having in a query that is not a "CONNECT BY" clause that is clearly not the case here. I suspect it's because you use analytical functions 'LEAD' and 'LAG '. I took your statement, replaced the names of table and column with some in a table, I also has a structure of hierarchical and got the same error. After removing all the functions of 'LEAD' and 'LAG' it run OK.
I don't think that helps you all.
You may create another table with the contents of this table by adding 4 columns for rownum, level (level) lead and lag (level). Then use this table to generate your unsorted list html code.
